98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.

108The following will add an entry C<a to b> that transforms all C<a>s in
109the selection to C<b>s, but only if the selection currently contains any

155Of course, this can be modified to suit your needs and your editor :)
156
157To expand the example above to typical perl error messages ("XXX at
158FILENAME line YYY."), you need a slightly more elaborate solution:
159
160 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163The first line tells the selection code to treat the unchanging part of
164every error message as a selection pattern, and the second line transforms
165the message into vi commands to load the file.
166
167=item tabbed
168
169This transforms the terminal into a tabbar with additional terminals, that
170is, it implements what is commonly refered to as "tabbed terminal". The topmost line
171displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
172button per tab.
173
174Clicking a button will activate that tab. Pressing Shift-Left and
175Shift-Right will switch to the tab left or right of the current one.

185
186This is basically a one-line extension that dynamically changes the background pixmap offset
187to the window position, in effect creating the same effect as pseudo transparency with
188a custom pixmap. No scaling is supported in this mode. Exmaple:

208=item selection-pastebin
209
210This is a little rarely useful extension that Uploads the selection as
211textfile to a remote site (or does other things). (The implementation is
212not currently secure for use in a multiuser environment as it writes to
213F</tmp> directly.).
214
215It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
216i.e.
217
218 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
219
220Pressing this combination runs a command with C<%> replaced by the name of
221the textfile. This command can be set via a resource:
222
223 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
224
225And the default is likely not useful to anybody but the few people around
226here :)
227
228The name of the textfile is the hex encoded md5 sum of the selection, so
229the same content should lead to the same filename.
230
231After a successful upload the selection will be replaced by the text given
232in the C<selection-pastebin-url> resource (again, the % is the placeholder
233for the filename):
